HI.
If A1 contains 10/07/2009, B1 will be :
=WORKDAY(A1,-1)
If you don't find the WORKDAY function, you must have to add the
Analysis Tool Pack add-in.

Hi,

If i have a date, say 10/07/2009 and i want to have a series of cells next
to it that return the previous weekday, say 09/07/2009...and then if i change
the first cell, all of the corresponding cells update. Thanks everyone.
